The Open Service Access (OSA) defines an architecture that enables service application developers to make use of network functionality through open standardized interface, i.e. the OSA APIs and Parlay X Web Services. The network functionality is describes as Service Capability Features (SCFs) or Services. The OSA Framework is a general component in support of Services (Service Capabilities) and Applications. The concepts and the functional architecture for the OSA are contained in the present document. The requirements for OSA are contained in TS 22.127.

Note:  The terms "Service" and "Service Capability Feature" are used as alternatives for the same concept in the present document. In the OSA Application Programming Interface (API) itself, the SCFs as identified in the 3GPP requirements and architecture are reflected as "service", in terms like service instance lifecycle manager, service Discovery.
